THR has confirmed that The Expendables 4 is coming and will hit theaters in 2018, and it will be the "final" movie of the franchise. Think that will stick if it makes $300M? Me neither. So far there aren't any details or further casting beyond Sly, Statham, and the Governator. But let's be honest; the rest of the team will find time in their schedule for a paid vacation where they occasionally scream, flex their muscles, and blow stuff up.
The only other questions are who will direct and which old school action hero will show up? I expect Jackie Chan will finally arrive because it's been teased for years. Think Bruce Willis will come back after pissing everybody off the last time? Maybe. Who is left? Dwayne Johnson??????
